To (ZZZ 407mm it may concern lie it liilOWi'l thui ii, Emvunn innn, citizen ihc lilnitcd Slates. residin at ii/1 m u. .4. w a noon]. in inc coumy oi: Miudlesex and clinic o z ssachuscuts, havc invented a new and use]. ll i llli lng for Radiators, of "which lhe ii'illowing s a specification.

ihis invention relates to fitting for use in C-OlillCCblOIl wi h hot Water radiators ouch by means of which it becomes necessary to utilize bub a single tappin Hcrctoiore it has been the practice to provide a tapping at each end of a Tediator and to connect separate pipes to the solo toppings, this oi tcn necessitating tearing up floors in order that pipes might be extended to both ends of the radiator. Such an arrangement is also objectionable because it is impossible to add to or subtracb from she nuinbcr of radiator sections employed without changing the pipe connections.

it has been found in practice that the foregoing objections can. be eliminated by having two tappings, one beside the other, in one end or the radiator, and connecting separate pipes to each. This, however, is objectionable because of the additional expensc involved.

One of the objects of the present invention is to provide a fitting for use in con nection With a single tapping, to which the flow and return pipes may be connected, said fitting being so constructed as to direct the hot Water into the radiator where it will rise WltllOlli} mixing to an appreciable extent with the discharging cool water, thus materially reducing the cost of installing hot Water radiators and permitting the work of roughing in the piping to be done with absolute accuracy.

lVith the foregoing and other objects in View which Will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the dci-ails of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made Within the scope of what is claimed. Without departing from the spirit of the invention.

In the accompanying drawings, ihc prerfcrred form oi the invcnlil'm has bccn shown.

In said drawings: Figure l is a perspechive view of u porlion of c radiator {and showii'ig the fitting applied thereto d con" is a plan view of thcviitting. Fig. 3 is an endelevaiiion. of the fitting viewed from that end tl'iereaii to be connccied to a radiator.

Referring to the figures by characters of reference 1 designates a i fitting having a threaded end 2 adapted to be screwed inco a single tapping inponc end of a radiator A while the branches of the fitting are interior-l y scrow threaded, as shown at 3 and open into the filling it opposi're sides of an S- shnpeddiaphragm l extending longitudinally within the iitiing aiulsub-dividing it into two nonconiinunicaiing compartments. is shown in big. 2, this diaphragm does not exl'end beyond the open end of the fitting but. lieiin'iinnies iiush ilu-reuilih. The branches of ihe iiiiing are zulapicd to be connected, by nipples 5 to ihe valve 6 of he hot wuicr flow pi pipe ii;- will-be note diaie portion of tho diaphragm 1- is perpendicular lo the plan ccupiedby the axes of the branches of the filling so than? as long as these branches are disposed in the some horizoniul plane, the diaphragm will always have. its iiuicrinediate portion extended ver tic-ally. As a resulr, as hot water passes through the filling to the inlerior of the radiator, it will rise above the cooler Water leaving the lLLLililiOl through the fitting, thus insuring the discharge ()5 the Water through that branch of the fitting opening into the return pipe 8 without it mixing, to on Ohectionahle extent,

with the hot- Water entering the radiator through the other compartn'ient within lhc fitting. This c1rculation is insured primarily because of the fact that the greater portion. of the area of the compartment ,-o1nn'iunicaiin g with {he rot-urn pipe is located below the center of the suing whereas the grcalerpmiion of the area of the feed conipml mentof the hiking is 10- cutcd above the cooler oi rho fittin g'lhc hot water will thus enter in a large stream, above the outflowiug current of cooler Water and will rise pronipily to the top. of the radiator with but lillle interference.

It. is to be understood that this dcvicedocs note-bruins the use oif any particular form of valve or valve connection or any change in the constriujrliou oi the radiator. It is to be sppl' co the usual type of radiator and in izhe ciruinnry nipping employed. in ($011" and to a return" d [but he interino lea nectio'n therewith, the branches of the fitting being connected to the ordinary valve, 6 and to the feed and return pipes commonly used. It will be apparent that, by employing a fitting such as described, the size of the comes unnecessary to extend the diaphragm 'or any other part into the radiator. While the sameadvantages cannot be gained by using this fitting for connecting the How and return pipes to a single opening in a steam radiator, since the usual method of connecting steam radiators is to dispense With the rcturn pipe and allow the condensed Water to return to the boiler in the bottom of the same pipe in which the steam is conveyed to the radiator, the same fitting could be used if two pipe Work should be' desirable.

\Vhat is claimed is 1. A radiator fitting including branches, and 'an S-shaped diaphragm extending longitudinally Within the fitting and forming noncommunicating compartments opening into' the respective branches, one of said compartments overhanging the other compartment throughout its length.

2. A radiator fitting including branches, a diaphragm extending longitudinally within the fitting and forming noncommunicating compartments openin into the respective branches, said diap ragm being 8- shaped in cross sectional contour throughout its length, one of the compartments in the fitting overhanging the other compartment.

3. A fitting for radiators, including branches, a diaphragm straight from end to end and extending longitudinally within the fitting from one end thereof to a point between the branches said diaphragm being S-shaped in cross sectional contour throughout'its length and tornnng opposed similar compartments straight from end to end, one

of the compartments overhanging the other 5 compartment throughout its length irrespective of the position to which the diaphragm is rotated.

In testimony that I claim the foregoing as my own, I have hereto afiixed my signature in the presence of two witnesses.
